TOOTHACHE

Is your address book open to the world? Is your mobile phone calling Russia? Many users don’t know how easy it is for an attacker to target Bluetooth.

Do you remember the friendly young man with the laptop sitting next to you on the subway this morning who got off one station before you did? Now he knows all about your appointment with the doctor tomorrow afternoon; he knows your girlfriend’s phone number; he’s read the messages your co-workers sent you after the meeting yesterday. In fact, he’s read all your messages and the phone numbers on your cell phone too. And, incidentally, he justchanged your appointment with the boss by one hour. You’re going to be late, and you can forget about that promotion.
